Perhaps this is too pragmatic, but here are my hesitations regarding the issue:
1) It seems illogical and irrational to put people on airplanes and take them thousands of miles from their home, to a place where they know nobody, know not the language, nor possess the resources to succeed, when there are dozens of adjoining countries they could take refuge in. Further, isn't the idea that they'll return home once things are safe?
2) I don't know how anyone ever trusts the federal government to do anything correctly, particularly this exceedingly incompetent administration, particularly on this issue, and as such have zero confidence that they'll properly screen any isis people. It seems like erring on the side of caution may be warranted under these circumstances. Send the other countries money if you want to help.
